Perhaps someone more knowledgable can confirm this but I personally think there was a choice when it came to ordering and specifying the paintwork on early Esprits. My gut feeling tells me that the customer could choose either to go black or body colour with the wing mirrors and bumpers (possibly even the hatch louvres on later cars) and also whether to have the wheels (clearly when I say early Esprits I mean post compomotive) all silver or with a coloured centre. On the price list at the time (1981 is the one I have)!it states "individually styled paint & coachwork" which ties in with my thinking......
I would love someone in the know from back then to confirm though. There are too many that still remain that appear unchanged from new ie. once owners carry out paint modification work and they can see what's under the top cost of paint, for this not to be true in some way I think
